播放2.0 / 2.1 Java和依赖注入(Play 2.0/2.1 for Java and de

We have a new Play 2.0 project and we are planning to introduce DI as we add some complex 3rd party integration code.

There is a Guice plugin for Play 2.0 but it looks like it will be obsolete at 2.1 and I have a hunch that 2.1 is not that far anymore.

Is Guice a safe bet for Play 2.0/2.1 or should we consider other options?

Answer 1:

我用2.1版本，并从全局对象的新控制器instanciation去。

下面是从一个Guice的例子DOC ：

  import play.GlobalSettings;

  import com.google.inject.Guice;
  import com.google.inject.Injector;

  public class Global extends GlobalSettings {

    private static final Injector INJECTOR = createInjector(); 

    @Override
    public <A> A getControllerInstance(Class<A> controllerClass) throws Exception {
      return INJECTOR.getInstance(controllerClass);
    }

    private static Injector createInjector() {
      return Guice.createInjector();
    }

  }

你必须申报这些控制器一种特殊的路由，与特殊@ ：

GET    /myUrl       @controllers.MyController.myMethod()

而且你还可以使用看看这个演示春季： https://github.com/guillaumebort/play20-spring-demo
